In this image the archer has begun putting tension on the cord, drawing it tight, and has also bent the wrist in order to get proper placement of the fingers around the arrow and the nocking point.
This is the minimal amount of slack, best for introducing the archer to the formmaster. Once the archer is able to truly engage the back, and use proper alignment, the string should be made to be much more slack - 1 to 2 inches . Putting too much slack in the string for an archer NOT able to align properly and to use the trapezius muscles properly WILL risk injury to the archer!
As the draw proceeds she will be able to straighten out the wrist and still
contact the bowstring with her tab/fingers.
NOTE also the clamp on the cord is oriented so that the threads will not touch/scratch the archer's forearm.
